دوره VMware vSphere Optimize and Scale که همزمان با نسخه vSphere6 منتشر شده است، جایگزین و تلفیق از دو دوره vSphere Troubleshoot وvSphere Performance Tuning می‌باشد.
برای شناخت کارشناسان و مهندسین سیستم های مجازی‌سازی با مباحث فوق تخصصی در جهت راه اندازی، مدیریت، عیب‌یابی و بهینه‌سازی زیر ساخت VMware vSphere طراحی شده است.
فرد در این دوره علاوه بر رفع مشکلات واقعی و طبیعی VMware vSphere در آزمایشگاهی با تجهیزات سخت‌افزاری کامل، اقدام به یادگیری مواردی کاملا کاربردی جهت بهبود کارایی
در زیرساخت مجازی‌سازی شده خواهند نمود. علاوه بر این مواردی حیانی که هنگام مجازی سازی سرویس‌های شبکه به منظور افزایش کارایی باید رعایت شوند مورد بررسی قرار خواهند گرفت.
آنچه خواهید آموخت
آشنایی و تسلط بر موارد زیر:- استفاده از vSphere client و دستورات CLI جهت عیب یابی مشکلات بر روی سرویس دهنده ESXi- معرفی و استفاده از vSphere Management Assistant یا vMA جهت رفع مشکلات سرویس دهنده های ESXi و vCenter Server- استفاده از محیط CLI جهت عیب یابی vMotion, SVMotion, HA, DRS- استفاده از vSphere Client جهت ردیابی و رفع عیب ماشین های مجازی در محیط VMware vSphere- بکارگیری تمهیداتی جهت بهینه سازی در کارکرد CPU- بکارگیری تمهیداتی جهت بهینه سازی در تخصیص Memory- بکارگیری تمهیداتی جهت بهینه سازی vNetworking و Storage
